The Scala (XLA) project, formerly know as Torque (XTC), and Stellite (XTL) prior to that, may have some controversy surrounding it along the way, but we are not going to be talking about that. The project has just released their Scala Mobile Miner v1.0.0 intended for Android smartphone owners to mine XLA on their devices and we just wanted to give it a go and see how it works, but more of that in a moment. Scala (XLA) uses the s called DefyX algorithm for mining. DefyX is a customized hybrid algorithm combining RandomX, Kangaroo12 and Yescrypt with the memory requirements optimized to fit more energy-efficient CPU and ARM architectures according to the developers. Apart from Android smartphones that can just now be used to mine Scala (XLA) coins, you could use a normal computer processor to mine with significantly higher hashrate for quite some time already.

Let us take a look at the Scala Mobile Miner software that you need to download directly as an APK for the moment and manually install as it is not yet available on the Google Play store. We like the fact that the apps starts with a warning message noting the important things regarding the battery and CPU having a high load on your smartphone. Then at the Settings screen there are the options for how many of the CPU cores to use and what temperatures to maintain as safe for both the processor and the battery. Then all you have to do is choose a mining pool and set your worker or wallet for the pool in order to start mining.

Now as far as mining is concerned you should not expect too much from a smartphone, even if it is top of the line Android smartphone. We have tested with Huawei Mate 30 Pro and got around 50 H/s as hashrate with 4 out of the 8 CPU cores active. If running with full 8 cores the CPU thermal threshold of 65 degrees Celsius is reached immediately, not to mention that you still would want to be able to use your phone while the miner is running on the background. With 4/8 CPU cores for mining it is possible, not draining that much battery and keeping reasonable operating temperatures for both the processor and battery.

So in short we like the Scala Mobile Miner, it is well made and works fine maintaining the safety and usability of your device. As far as performance is concerned, well there is more to be desired, especially if you compare the hashrate of just around 50 H/s to a high-end desktop CPU such as Intel Core i7 6850K or AMD Ryzen 3900X like we did and you can see the results below:

Intel Core i7 6850K (6C/12T):
– XLArig 5.0.1 – 2100 H/s
– SRBMiner-Multi 0.4.0 – 4650 H/s

AMD Ryzen 3900X (12C/24T):
– SRBMiner-Multi 0.4.0 – 11970 H/s

The latest official XLArig 5.0.1, based on XMRig, is not the best performing miner at the moment with support for the DefyX algorithm used by Scala (XLA). You should opt out for the latest SRBMiner-Multi 0.4.0 significantly better hashrate for mining Scala (XLA) using the DefyX proof of work algorithm. Do note that the DefyX algorithm has been used for a while already by the Scala project and prior to that XLA coins were mined using CryptoNight algorithm, so it is both not a new project and not a new algorithm.

Latest Crypto Fear & Greed Index

The website analyzes emotions and sentiments from different sources and crunches them into one simple number called The Fear & Greed Index for Bitcoin and other large cryptocurrencies. The crypto market behavior is very emotional. People tend to get greedy when the market is rising which results in FOMO (Fear of missing out). Also, people often sell their coins in irrational reaction of seeing red numbers. The idea of the Fear and Greed Index is simple – to save you from your own emotional overreactions. Extreme fear can be a sign that investors are too worried and that could be a buying opportunity, while when Investors are getting too greedy, that means the market is due for a correction.

The different factors that create the value of the Crypto Fear and Greed Index are: Volatility (25%), Market Momentum/Volume (25%), Social Media (15%), Surveys (15%), Dominance (10%) and Trends (10%). The current value of the index is 14 which is considered Extreme Fear and you can see the results in the price drop of Bitcoin and other major crypto currencies in the last few hours. It is interesting to note that yesterdays index was at 17, so Extreme Fear as well (though slightly less than today). Do note that the lower the number, the higher the Fear is, the higher the number, the higher the Greed is. And in situations of Extreme Fear come the good opportunities, though do not forget that risk is also high!

A few days ago we have mentioned the Handshake (HNS) project and the fact that mining has recently started with GPUs and FPGAs that offer slightly faster hashrate at a bit lower power usage and that ASIC miners are also going to be coming out soon. Now there are more details about the first announced Handshake ASIC miner available from the Chinese ASIC manufacturer Hummer Miner with their device up for pre-order. The Hummer Miner Mars H1 ASIC should be offering 80 GH/s hashrate with 2000 Watts of power usage (25 Watt/GHs efficiency) and is priced at 12600 CNY or roughly about $1800 USD with shipping expected to start mid-June and not in May as previously expected. This gives some additional time for miners with GPUs and FPGA’s from Hashaltcoin to stock up on HNS coins before ASIC miners hit the market, even though profitability is already getting lower day by day as we are seeing.
